摘　　要：将具有优良环保性能的二甲醚作为制冷剂应用于冰箱,对其制冷性能进行了详细的理论计算和分析,在二甲醚为灌注式的条件下,对冰箱的主要制冷性能进行了实验研究.结果表明:充灌二甲醚的冰箱与采用原制冷剂CFC12的冰箱的各项性能指标接近;实验冰箱二甲醚的最佳充灌量为54g,24h耗电量为1 087kW·h,比采用CFC12节能15.6%;在不改变原冰箱结构的条件下,用二甲醚作为制冷剂是可行的.The performances of the refrigeration cycle of dimethyl ether (DME) used as a refrigerant for refrigerators were theoretically calculated and analyzed. The experimental study on the main performances of refrigerator refrigeration cycle was done by using DME substituting for CFC12 under the condition of unchanged original refrigerator construction. The experimental results indicate that the performances of the refrigerator using DME or CFC12 are nearly the same, and the optimal charge amount of DME in BCD-218 refrigerator is 54 g, the energy consumption per day of DME is 1.087 kW&middoth which is only 84.4% of that of CFC12. Therefore the refrigeration performance of refrigerator using DME can still meet the national standard requirement under the condition of its optimum charge amount.
